I did a fresh install of Windows 10 on my PC the other day. I tried to load up MultiMC (which is the application I create and play my modpacks on) but it said that my Java was either moved or missing or something like that. And when I looked in my "mods" folders, all of the mods (which are .Jar files) didn't appear to have the little Java icon next to them indicating that they where .Jar files. Instead they where just the default note icon you would usually get on a text document file. So I assume from this I don't have Java installed. So I'll have to install it again but I'm not entirely sure what version of Java I should install. Does it depend on the version of Minecraft it is? Or what type of mods I'm using? Or how many mods I'm using? I'd like some suggestions and if it helps I'll list what version of Minecraft I have and the mods I have installed for it. I only use MultiMC to create and play my modpacks with. I do not use the Minecraft or Technic launchers. Also another question I have is, will installing Java again require me to reinstall my mods also? It's just been an awfully long time since I installed Java, I kinda forgot how it all played out
Check these out. If you are confused, it helps to know: what version of Minecraft you are using, and what modloader you are using (Fabric vs Forge). How much RAM your computer has also matters; later modded versions and more/bigger mods need more RAM to run properly.
My computer has 16GB of RAM so would I be okay with that front? Also, the version of Minecraft that is associated with my modpack is 1.7.10 (I have already installed the recommended forge version for it too although I'll have to check back to you on what that forge version is considering I forgot). I have around 40-50 or so mods installed for it at the moment (including all the compatibility and core mods to help the actual mods run). I currently have 5G of RAM allocated to it, but I'm planning on increasing it in future when I add a few more mods. Would Java 8 64 bit be a good option still?
Oh yea, 16GB should be plenty even for modern packs, but for 1.7.10? Yea, Java 8 64-bit is still the way to go.
Edit: Also, maybe press F3 while in-game and see the RAM usage. You may be allocating a lot more RAM than you need for that version and mod count, but then again it varies a lot depending on what kind of mods you have installed, settings, etc.
